    Citel Outdoor Power-Over-Ethernet (POE) Protector

    The CMJ8-POE is an outdoor PoE surge protector designed to protect sensitive data-processing equipment connected to a PoE (Power over Ethernet) network from transient overvoltages. The CMJ8-POE surge protector is deployed in signal network applications with data transmission speeds up to 1000 Mbps and is equipped with high quality shielded RJ45 connectors. The transient protection circuit is based on high energy gas discharge tubes (GDT) and a network of fast response silicon avalanche diodes (SAD's) to achieve sharp clamping of very large surge events.
